Understanding how pedaling and power transfer work is key to improving your cycling performance. By optimizing your pedaling technique and ensuring proper maintenance, you can maximize your power output and ride more efficiently.
Gearing and Shifting
Understanding how gearing and shifting work on a bicycle is crucial for any cyclist. Gearing refers to the different combinations of gears available on a bicycle, while shifting is the process of changing between these gears. By changing gears, cyclists can effectively control the amount of effort needed to pedal and maintain the desired speed.
On a bicycle, the gears consist of chainrings (located at the front) and cogsets (located at the rear). The chainrings are attached to the pedals and determine the gear ratio, while the cogsets contain multiple cogs of different sizes. By combining different chainrings and cogs, the cyclist can choose from a wide range of gear ratios to suit various terrains and riding conditions.
How does shifting work?
Shifting gears on a bicycle is made possible by the use of derailleurs. A derailleur is a device that moves the chain from one cog to another, allowing the cyclist to shift gears. When the rider operates the shifters, derailleurs move the chain onto a different cog, resulting in a change in gear ratio.
There are two types of derailleurs commonly found on bicycles: front derailleurs and rear derailleurs. The front derailleur controls the movement of the chain between the chainrings, while the rear derailleur moves the chain across the cogset. By using the shifters attached to the handlebars, cyclists can control the derailleurs and shift gears as needed.
How does gear ratio affect the bicycle?
The gear ratio determines the relationship between the rotations of the pedals and the distance traveled by the bicycle. A lower gear ratio, such as when using the smaller chainring and larger cog, allows for easier pedaling but slower speeds. This is ideal for uphill climbs or when starting from a standstill. In contrast, a higher gear ratio, achieved by using the larger chainring and smaller cog, requires more effort to pedal but allows for faster speeds. This is suitable for flat roads or downhill descents.

Braking and Stopping
Braking is an essential aspect of how a bicycle works. When riding a bicycle, it’s important to have control over your speed and be able to stop quickly when necessary. The braking system on a bicycle allows you to slow down or bring the bike to a complete stop.
The most common type of braking system on a bicycle is the rim brake. This type of brake uses friction to slow down the bicycle. When you squeeze the brake lever, it pulls a cable that moves the brake pads to make contact with the rim of the wheel. The friction between the brake pads and the rim creates resistance, which slows down the rotation of the wheel and eventually brings the bicycle to a stop.
Another type of braking system commonly found on bicycles is the disc brake. Disc brakes work on the same principle of friction but use a rotor and caliper instead of the rim. When you apply the brake lever, hydraulic fluid or a cable compresses the caliper, which then squeezes the brake pads onto the rotor. The resulting friction slows down the rotation of the wheel and stops the bicycle.
It’s important to note that the braking system on a bicycle doesn’t immediately bring the bike to a stop. The stopping distance depends on various factors, including the speed of the bicycle, the condition of the braking system, and the force applied to the brake lever. It’s crucial to anticipate the need to stop and start applying the brakes in advance to allow enough time to slow down or stop safely.
When riding a bicycle, it’s also essential to understand the concept of weight distribution when braking. The weight of the rider and the bicycle is transferred to the front wheel when braking, which increases the traction and allows for more efficient stopping. However, applying the brakes too abruptly or with excessive force can lead to a loss of traction and cause the bicycle to skid or topple over.
Overall, braking plays a vital role in how a bicycle operates and allows the rider to have control over their speed and bring the bike to a stop safely. Understanding how the braking system works and practicing proper braking techniques are important for every cyclist to ensure a safe and enjoyable ride.
